TELEPHONE=TRANSWHTTER SUPPORT.

SPECIFICATION forming part of Letters Patent No. 745,049, dated. November 24:, 1908.

Application filed November 24, 1902. Serial No. 132,563. (No model.)

To all whom, it may concern:

Be it known-that I, AUGUSTE GAMACHE, a

subject of the King of Great Britain, residing at East Clifton, county of Compton, Province of Quebec, Canada, have invented certain new and useful Improvements in Telephone- Transmitter Supports; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to Whichit appertains to make and use the same. p Myinventionrelatestotelephone-transmitters; and its object is to provide simple means for supporting the transmitter, so that it may be moved to different heights to accommodate the diiferent persons who may use it, this change of height of the transmitter not affecting the direction of the mouthpiece.

The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims.

In the drawings, Figure 1 represents my invention substantially in side elevation, the same being partially broken away, as indicated. Fig. 2 is substantially a front elevation of the same, a portion being shown in section, as will appear. Fig. Sisarear elevation.

Throughout the specification and drawings the same numerals of reference indicate like parts. Y

Referring more particularly to the parts, l represents a transmitter, which, as shown, is provided upon its rear side with outwardlyprojecting lugs 2, through which pass substantially horizontal pins 3, which are rotatably mounted in transverse heads 4, carried upon the extremities ofthe arms 5. arms are preferably tubular in form and two in number. Attheir rear extremities they are provided with heads 6, which are rigidly mounted upon arbors 7. These arbors are preferably of relatively large diameter, as shown, and are horizontally disposed. I provide means for clamping them, so that they may support the arms 5 simply from the frictional resistance which is offered to their rotation. To this end I provide a base 8, consisting, substantially, of a box open upon its rear side and preferably made of Wood, its side walls 9 being preferably provided with counterbored openings 10, adapted to receive These l fastening devices, such as screws, for attaching the same to awall or similar support. This base is provided with a face-plate 11, upon which are mounted suitable bindingposts 12. In front of this face-plate there is provided a member 13, which is of substantially the form of the large letter l-l, its vertical side members 15 being united by a bar or tongue 14.-. In front of these side members 15 there are provided the fiat vertical members or strips 16, and the adjacent faces between the same and said members 13 are formed into recesses 17 and 18, respectively. These recesses receive between them the extremities of the aforesaid arbors 7, conforming substantially to the diameter of these arbors. Thumbscrews 19 are provided, preferably four in number and having milled heads 20, which pass through nuts 2l, set into recesses 22 in the side walls 9 of the base, as shown, and

by tightening these screws the members 16 may be clamped firmly upon the arbors 7, wherefore they are more or less securely held, so that they may support the transmitter 1 in a fixed position, but at the same time permitting the transmitter to be raised or lowered, as desired. The members 16 are attached to the members 13 also by means of screws 23, as indicated, which pass through the members 15 from the rear. This additional attaching means between the members is for the purpose of holding the strips 16 in be changed in position, but not in direction. In this manner the axis of the mouthpiece 24 is always substantially horizontal, as it should be.

The circuit-Wires 25, which pass through the rear side of the transmitter, are conducted to the base through the tubular arms 5,

IOO

Which are provided with openings 26 for this purpose.

While I have shown in the accompanying drawings the preferred form of my invention, it Will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position Without affecting the operativeness or utility of my invention, and I therefore reserve the right to make all such modifications as are included Within the scope of the following claims or of mechanical equivalents to the structures set forth.

Having described my invention, what I consider new, and desire to secure by Letters Patent, is-

1. In combination, a base, a member adapted to be placed thereupon, atransmitter, arms adapted to support the same, said arms being formed into arbors at their inner extremities, other members adapted to clamp said arbors to said first member, clamping-screws passing through said members, and means independent thereof for attaching said members together.

2. In combination, a transmitter, arms adapted to support the same, trunnions carried by the inner extremities of said arms, a member comprising parallel side pieces, said side pieces having recesses therein adapted to receive said trunnions, clamping-strips adapted to firmly clamp said trunnionswithin said recesses, and means independent thereof for attaching said strips to said mem# ber, said member being adapted to support said arms.

3. In a telephone, the combination of a transmitter base having. projecting side pieces, the latter having semicylindrical recesses therein, a pair of clamping-plates mounted parallel to said side pieces and having corresponding semicylindrical recesses, clampingscrews arranged to screw said clamping-plates against said projecting side pieces, a pair of swinging arms having cylindrical cross-heads forming axles therefor, said cross-heads having their ends journaled in said recesses, and a telephone-transmitter pivotally mounted on the free ends of said arms, the latter being parallel in all positions, whereby to cause said transmitter to remain parallel to itself and to permit the same to be adjustably supported.

4. In a telephone, a stationary base comprising a box adapted to contain electrical apparatus and having projecting vertical side pieces, ends pieces connecting them, a faceplate closing the front of said box, bindingposts mounted on said front plate, a swinging arm pivoted on said projecting side pieces, a clam ping-plate adapted to adjustably regulate the friction of said swinging arm, and a telephone mounted on the free end of said swinging arm.

5. A telephone-transmitter support comprising a base having vertical side pieces, a pair of vertical strips 16, said side pieces and strips having semicylindrical recesses therein, clamping-screws adjustably binding each strip to its respective side piece, a pair of parallel bars 5, each formed with a cross-head 7 socketed in said semicylindrical recesses, and a member 2 connecting the free ends of said parallel bars.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.
